Well, somehow I've been under impression that the change would bring 
more significant results. Here we can see slight reduction in lines of 
code, but also slight increase of kernel image size. Still, in general, 
nothing extreme.

In this case I'd probably go with Rahul's original code, as it doesn't 
require second matching and separate match table, which adds redundant 
compatible strings used just for this extra matching pass.

I guess this is all just bike shedding, though.

Best regards,
Tomasz
